Home Insulation & Air Sealing Company

Many homeowners are under the impression that their home is properly insulated. However, when we take a look we find that the majority of homes do not have the proper amount of insulation. We find the wrong types of insulation used, insulation in the wrong locations, gaps in the insulation and in some cases no insulation at all. What does that all mean? It means you are spending far more money than necessary to keep your home comfortable. Stop wasting money, contact the professions at Halco today!

The idea of home insulation has been around for centuries. Cavemen lived in caves because of the natural protection it afforded them. Modern dwellings do not naturally keep the inhabitants warm and comfortable, insulation must be added to get the job done. Pink fiberglass insulation was used for decades but now Polyurethane spray foam is the best product available.

Benefits of Spray Foam Insulation Include:

  • spray foam works in all areas of the home
  • has a greater R-value
  • acts as an air sealant
  • is waterproof
  • leaves no gaps

By adding additional attic insulation, you will make your home more comfortable and save money on your energy bills.

We all know that heat rises and as a result attic insulation can have a major impact on the efficiency of your home. When you are heating your home in the colder months that heat will rise and escape through your attic. Depending on the size of your home the amount of heat that will escape could be equivalent to keeping a window open.

In a national study, the average R-value found in an average attic is R-19 while the U.S. Department of Energy recommends an R-value between R-49 and R-60. Halco has the trained professionals who will be able to give you certainty about the attic insulation in your home and its overall efficiency. Call or click today to Save up to 20% or more in heating and cooling costs with a properly insulated attic!

I am currently building a 12 sided house in Groton NY and am considering getting spray foam insulation in the roof as well as a few other locations. Do you provide free estimates? If so I would be happy to review the project with you some evening. Thank you

Hi Halco, I would like to request a quote for two possible systems: 1. Geothermal to provide hot water for baseboard heating and hot water, replacing a fuel oil furnace. The house is around 2k sqft. 2. The geothermal above and an 11-12 kW pv solar setup. Thanks, Bryan Gorges
Project Location: Groton, NY
Technician replaced the gas valve, everything seems great. However he also found the exhaust vent was allowing exhaust to enter the intake since they were adjacent and the vent had a 90° T, venting directly next to the intake. He removed the T, which made sense. So now the vent exits directly from the house. However, looking at it, I am a little concerned since the vent is just an open pipe 3 ft or so from the ground, sticking out about 6 inches. Shouldn't there be some kind of cap on the end to prevent weather (rain/snow) and critters (mice/birds) from entering but still allow venting away from the intake? Just looking for a second opinion - perhaps the tech didn't have the appropriate part? I can email a photo of the vent if you wish. Thanks, Greg Weiland

I have an old & inefficient gas-fired residential Weil-McLain Boiler. I was told a year ago it would need replacement "soon". So, I'm looking to get it looked at, and understand what a replacement will cost. I'm open to other suggestions for heating as well.

I just bought a house and would like to know how energy efficient it is. It's drafty in some places and needs a new furnace
Project Location: Groton, NY
We had a geothermal system installed 2 years ago, which has run flawlessly and saved us about 2/3 off our heating bill. UNfortunatly, we recently have had some problems with the system. The heat pump wont stay on very long, therefore not allowing the water temperature to heat up enough for the air handelers. One of the lines serving the loop field has developed a leak where the line enters the flow center. I'm also told that some of the plumbing may have been installed incorrectly, and the temperature senser for the storage tank is also in the wrong place. The company that installed the system has gone out of business (Gleason). I would like to arrange a service person to come out to see if we can diagnose the problem and put together a quote for the needed repairs. It is a GeoComfort brand heat pump. The system has been down for about 2 1/2 weeks, but we have been comfortably heating with wood in the meantime. I should be able to be reached most of the day on Friday 2/8, but my schedule varies. Maybe we can set something up early next week after the winter storm passes. Thank you.
